Hamilton Conducell 4US sensors are quality products manufactured with the latest technology.
These instructions should be read, understood and followed by all staff using the device.
Hamilton can assume no responsibility for damage and operational disruptions arising from
failure to observe these instructions.
1 Liability
The Liability of Hamilton Bonaduz AG is detailed in the document «General Terms and Conditions
of Sale and Delivery (GTS)», chapter 12.
Hamilton is expressly not liable for direct or indirect losses arising from use of the sensors. It
must in particular be insured in this conjunction that malfunctions can occur on account of the
inherently limited useful life of sensors contingent upon their relevant applications. The user is
responsible for the calibration, maintenance and regular replacement of the sensors. In the case
of critical sensor applications, Hamilton recommends using back-up measuring points in order
to avoid consequential damages. The user is responsible for taking suitable precautions in the
event of a sensor failure.

2 Intended use
With the Conducell 4US line, Hamilton has developed a family of in-line conductivity sensors
which perform under demanding conditions in biotechnology and the general chemical industry.
During development, special attention was paid to an optimum sanitary design. All materials in
contact with the solution are FDA approved.
The sensors are based on the 4-electrode principle which excludes polarization phenomena
normally observed with 2-electrode sensors. The engineered design guarantees an excellent
linearity over a conductivity range of more than 6 decades.
3 Safety
This sensor is to be used only as intended and is to be kept in a condition that ensures complete safety. The specifications given in the section «Technical Data» as regards temperature,
pressure etc. may under no circumstances be exceeded.
Inappropriate use or misuse can be dangerous.
Assembly and maintenance may only be done by trained personnel.
During assembly, ensure that the positioning is correct and that the O-ring is undamaged.
O-rings are consumable items and must be replaced regularly – at least once a year.
The built-in temperature sensor should only be used for compensation of conductivity, not for
controlling the process temperature.
Conducell 4US sensors are used to determine electrolyte conductivity in solutions. If these
sensors are used in potentially explosive atmospheres, see the section «Instructions for use in
potentially explosive atmospheres».
Every product for shipment or sent back for repair must be decontaminated. If working with
hazardous liquids observe and carry out the maintenance procedures, paying particular attention to cleaning and decontamination. If the product becomes contaminated with biohazardous,
radioactive or chemical material, it should be cleaned.
4 Initial operation
This Conducell 4US sensor has been carefully tested and is ready for use. During unpacking,
please check for any mechanical defects. In case of a complaint please return the Conducell
4US in its original packing to Hamilton and describe the problem.

range must stay within the specified input range of the instrument.
ATTENTION! The linearity of the system is strongly dependent on the instrument to which the sensor is attached. For applicable measuring range refer to
Technical Specifications of the manufacturer of the instrument.

6 Assembly
Please check if the process connection is sufficiently clean. Then fit the Conducell 4US.
Please follow the instructions mentioned below.
Examples:

Ø 60mm
min
ATTENTION! The cell
constant and the linearity
of the sensor can vary
with the fitting situation.
A symmetrical setup is
recommended. Leave an
open space of 60 mm
minimum diameter.
Partitions made of
non-conductive material
should preferably be
used.
ATTENTION!
A symmetrical setup is
recommended in order to
ensure a high degree of
linearity. To achieve high
precision the cell constant should be calibrated
in the final setup. Make
sure that all 4 electrodes
are completely and
continuously immersed in
the measuring sample.
Position marker
If the sensor is dismounted, the position marker helps to remount it in the original position.

MEASUREMENT • CLEANING • DISPOSALCALIBRATION
8 Calibration
There are two possibilities for calibration:
1) Calibration while sensor is disassembled from process:
• First, rinse the sensor thoroughly with deionized water.
• Use a beaker or container that has an (internal) diameter of at least 30 mm. (Conducell
4US fits perfectly into the Hamilton Conductivity Standards, and can be calibrated directly
in the bottle.)
• Use a solution of known conductivity. Check the temperature table of the conductivity
standard.
• Immerse the lower part of the sensor in the standard. Make sure that the 4 electrodes are
completely immersed. The sensor should be placed in the center of the beaker.
• Leave the sensor for at least 5 minutes for equilibration, before initiating the calibration on the
instrument.
For precise determination of the cell constant, it is recommended that you use an assembly
situation similar or equal to the situation in the process. The cell constant may vary with the
assembly situation.
2) Calibration in the process:
• Insert the sensor in the process.
• Leave conductivity and temperature at least 15 min. for equilibration.
• Take a process sample and perform an external measurement with a reference conductivity
system. The best approach is to perform the measurement at a temperature equal to that
of the process. If this is not possible, you need to know the temperature coefficient of your
sample (similar to temperature table on Hamilton Conductivity Standards bottle).
• Manually adjust the cell constant to read the same conductivity value on the process
instrument.
• You may switch off the temperature compensation of the process and the laboratory instruments to prevent any errors.
9 Measurement
Air/gas bubbles may stick to the sensitive area of the sensor. As a consequence, the measurement value might be wrong. In case of a shutdown of the power supply (230V) the measurement value could be wrong.
10 Cleaning
Conducell 4US can be cleaned with standard cleaning agents. Never use scouring agents
which contain hard particles. Please check the O-rings from time to time. When mounting the
new O-ring take care not to damage the O-ring nut or the O-ring itself. Otherwise the tightness
of seal can no longer be guaranteed.
If working with hazardous liquids observe and carry out the maintenance procedures, paying
particular attention to cleaning and decontamination.
Cleaning, assembly and maintenance should be performed by personnel trained in such work.
Do not use any abrasive tissues or cleaning materials and do not use any cleaning chemicals
other then described above. Before removing the sensor from the measuring setup, always
make sure that the setup is pressure-less and cold and that no process medium can be accidentally spilled. When removing and cleaning the sensor, it is recommended to wear safety
glasses and protective gloves.
11 Disposal
The design of Hamilton sensors minimizes environmental impact. According to the
EU directive 2002/96/EC the Hamilton sensors should be disposed as waste of
electrical and electronic equipment, and not in municipal waste, or it can be sent
back to Hamilton for disposal.
